When imagining 8.6 BLK, a good starting point is to think of 8.6 BLK as 300 BLK's "Big Brother." However, it's much more than just an upgrade on 300 BLK. 8.6 BLK is re-imagining "energy on target" by employing a fast 1:3 twist rate (compare to common 1:7 and 1:8 twist for calibers like 5.56 NATO or 300 BLK).

The trajectory of the 8.6 Blackout is about what you’d expect of a heavy bullet moving at modest to slow velocities, very rainbow-like. However, this cartridge wasn’t really designed to shoot out to 500 yards. The 8.6’s trajectory isn’t as flat as the 338 Federal, mostly due to the lower velocities of the Blackout. However, because of the higher B....
The energy of the 8.6 Blackout is just shy of double that of the 300 Blackout. Compared to the 338 Federal, it really doesn’t come close to the energy levels at any distance. Once again, aside from being somewhat similar dimensionally,the 8.6 Blackout was not made to compete with the 338 Federal. It was developed to do something entirely different....
The first is trajectory. The low velocities and the heavy, high ballistic coefficient bullets make these three almost identical in their trajectories. Their trajectories are so close that they are almost indistinguishable. The 8.6 Blackout and 375 Raptor are less than an inch apart at 400 yards. Out to 400 yards, all three bullets equally held thei...
The 300 Blackout and 8.6 Blackout both share something that sets them apart from the 375. Marketing. What does marketing do? It creates popularity that then builds a market around it. That growing market leads to options! The 300 Blackout has been popular for a while and has plenty of bullet options. The 8.6 is slowly getting more and more. For exa...
The 8.6 Blackout is a subsonic monster that uses a 338-caliber bullet at the same velocity and trajectory as the 300 Blackout. It outperforms the 300 Blackout in every category, such as energy, trajectory, and recoil. Learn how it compares to the 338 Federal and other subsonic cartridges in this article.
8.6mm Blackout (8.6×43 mm), also sometimes referred to as 8.6 BLK, is a centerfire rifle cartridge developed by the firearms manufacturer Q, LLC. It utilizes a shortened case from the 6.5mm Creedmoor necked up to an 8.6 mm caliber (8.585 mm or 0.338 in diameter) projectile. 8.6 Blackout is designed for use in bolt-action rifles or as a caliber ...

Apr 17, 2024 · The 8.6 BLK utilizes a 30-degree shoulder for a compact, consistent powder burn. A standard .308 bolt works with the 8.6 BLK, meaning only a barrel change is needed on AR-10s. The 8.6 BLK employs a radical 1:3-inch twist. This fast twist achieves fantastic accuracy with the 8.6’s heavy, subsonic bullets.
Feb 13, 2023 · 8.6 Blackout is a new cartridge design that shoots heavy .338 caliber bullets at supersonic or subsonic speeds for hunting or self defense. Learn about its advantages, disadvantages, and how to get one from this article that compares it to similar cartridges and provides photos of its performance.
Dec 3, 2022 · The 8.6 Blackout is a short-barreled rifle cartridge that can shoot supersonic or subsonic ammo for hunting deer, buffalo and more. Learn about its design, performance, ammo options and hunting applications from Q founder Kevin Brittingham.
Jan 28, 2022 · The 8.6 Blackout is widely spoken of as the “big brother” of 300 Blackout. The new caliber, developed by Q, completely re-imagines energy on target by using a faster twist rate – 1:3, compared to the popular twist rates of 1:7 and 1:8 for calibers like 5.56 NATO and 300 BLK.
